Tankathon is good, but my only gripe is that the order on tied teams is randomized.
I like Tankathon too...but I disagree with their Draft Power Rankings:
DRAFT POWER RANKINGS
1 Bos Boston 2, 11, 13, 18, 32, 36, 53, 59
2 Phi Philadelphia 1, 5, 23, 24, 39
3 Den Denver 7, 10, 15, 20
4 Sac Sacramento 3, 35, 57
5 Orl Orlando 6, 37, 45
In this scenario, I would rather have Philly's draft instead of Boston's.
